Buckler of Dark Souls
Buckler of Dark Soul Protection
This +3 Darksoul Protection Buckler is made of myriad small blades, darts, arrowheads, and other weapons hammered together to be hardly recognizable in the round shield, except for three adamantine-shafted arrows which stand out parallel to the arm. When used by an evil creature, it halves the damage of any effect which would be especially effective due to their alignment, such as a paladin’s smite evil attack, or the extra damage of a Holy weapon.
CL 9, protection from good, +4 shield, 16,165 gp
